A Rare Case of Gastric Lipoma with Early Gastric Cancer

抄録

An 84-year-old man was admitted to our hospital with a 1-month history of epigastralgia. Upper gastrointestinal endoscopy revealed gastric cancer and a gastric submucosal tumor (SMT) on the greater curvature of the gastric body. By endoscopic ultrasonography, SMT was demonstrated as a well-circumscribed, smooth-bordered and hypoechoic mass localized in the submucosal layer. Total gastrectomy was performed. The histology of the resected specimen revealed a gastric lipoma and an early gastric cancer widespread to the surface on the lipoma. Two lesions were present in the same lesion, but not linked. We report a rare case of gastric lipoma complicated with early gastric cancer.
